TO ALL WHOM IT MAY CONCERN: 4

Be it known that I, MARTIN BURTON, of Indianapolis, in the county ofMarion, and State of Indiana, have invented new and useful Improvementsin Steam Water-Elevators; and I do hereby declare that the following isa full, clear, and exact description thereof, reference being had to theaccompanying drawing, making part of this specification, in which-- I vFigure 1 is a vertical section.

Figure 2 is a section through the steam cock and steam pipes at theirjunction.

Figure 3 is a section view of n contemplated modification of one of thechambers, and of the float therein.

Similar letters of reference indicate corresponding parts in the severalfigures.

The following description will enable those skilled in the 'art to makeand use my invention.

- A and B are steam-tight chambers, which may beof either metal or wood.They communicate with each other at the bottom by means of the openconnecting pipe 0, from which a pipe, D, leads to the water. This pipeis furnished with a valve, E, as shown, to retain the water after it isdrawn up into the chambers A B. PipesG and H connect the chambers witheach other at the 'top, and a pipe, F, connects the pipes G and H with asteam boiler, (not shown.) At the junction of pipes F G H is a three-waycock, shown in section in fig. 2, of which N is the valve. This cock isarranged to alternately admit steam from theboiler into chamber B, andthen to cut 013' such admission of steam and simultaneously opencommunication between chambers 13 and A. This is eilected automaticallyby means of the float I, rod J, and lever K attached to the cock, ashereinafter described. The float I is a hollow piston, of metal or othersuitable material, possessing such buoyancy as to float upon water, andis made'to fit neatly but to move freely within the chamber B, the sidesof which should be parallel and quite smooth for this purpose. The rod Jpasses through a stuffing-box in the top of the chamber, and alsothrough the float, having free play in the latter. The rod is providedwith projecting flanges a a, above and below the float I, against whichthe latter strikes in descending and ascending, reciprocating the rod Jvertically. The upper end of the rod passes through the slotted lever K,which is attached to the valve N, and by means of the projections e e,above and below the lever, turns it to admit or out off the steam. Thefloat I is not rigidly attached to rod J, but moves frecly, up or down,without moving the rod until it engages with the projections a a, andconsequently the valve N is' not turned to open and close the ports topipes F and G until the float has descended to near the bottom, orascended to near the top of chamber B. The object of this arrangementfor operating the valve is to prevent any portion of the steam being cutoii' during the descent of the float, and, when cut off and condensed tocause a vacuum, it may not be re-admitted until the chambers are filledwith water, The float I may, however, be rigidly attached to the rod J,and the projections e 2 set apart so as to operate the lever K, to openand close the ports F andG by valve N in a similar manner as 1 abovrdescribed. The time of opening and closing the ports of pipes F and G,by the valve N, is adjusted by means of the movable projections e cabove and below the lever K, and by the movable ring a above the fioat.These projections being simple rings secured to the rod J by aset-screw, may be set at any position on the rod so as to engage withthe lever and float to operate the valve as may be desired. The valve Nmay be operated to open and close the ports of pipes F and G, with aquick movement, if desired,-by means of any of the wellknown devices inuse for a similar purpose. One method of doing this is here shown, butbeing no part of my invention I do not deem it necessary to describe it.Fig. 3 is a modification of chamber B, showing how it may be madehigher, and the float I longer in order to prevent the water rising highenough to wet and cool the surface of the upper part of the chamberwhere the steam comes in contact with it as the fioat descends; thusavoiding the condensation of the steam while employed to-drive the floatdown.

The operation of my invention is as follows Partly fill the chambers Aand B with water, though this is not absolutely necessary, as steam maybe admitted to fill the chambers and drive out the air, and a littletime allowed for it tocondense, when the water will flow in from thewell. Then raise the lever K up to the position shown in the drawings,which turns the valve N to admit steam from the boiler, by way of pipesF H to charm ber B. The steam forces the float I to the bottom of thechamber, driving the water contained therein into chamber A, and, ifmore than enough to till it, the remainder will be forced up intocduction pipe L. The valve M prevents the water from returning from thepipe to the chamber. When the float has descended to near the bottom ofthe chamber, by the means heretofore descr bed, the Valve N is turned toopen the port in pipe G and close that of F, simultaneously cutting oilthe steam from the boiler with opening communication between chambers Band A, allowing the steam to escape from the former to the latter, whichbeing filled or partly filled-with water condenses the steam, causing avacuum in both chambers that is immediately filled by the influx ofwater from the well by way of induction pipe D and connecting pipe C. IValve E prevents the water in the chambers from returning to the Well.The influx ot" Water to the chambers raises the float I, and when itascends to near the top of the chamber the valve N is operated,as'before described, to open the port of pipe F, which. again admitssteam to chamber B, simultaneously closing the port of pipe G andclosing communica. tion between the chambers A and B. The steam forcesthe float down, driving the water from chamber 13 into A and up pipe L,as before. Pipe L may extend to any desired practicable height, and thusthe device may be applied to elevating water for supplying cities,manufacturing establishments, or domestic use, in a simple andeflicacions manner. I

Having thus fully described my invention, what I claim as new therein,and desire to secure by Letters Patent, is

1, The arrangement of the chambers A and B, and pipes G, H, and C, inthe manner and for the purpose substantially as set forth 2. Thearrangement of the steam-induction pipe F, water-induction pipe D,eduction pipe L, and valves E, M, and N,-float I, rod J, and lever K,substantially as and for the purpose set forth.
